This invention `relatesto spraying apparatus and vmore particularly* to` an apparatus that is adapted to be used for spraying lubricant on vehicle springs, and for other analo- 1'5 gousf uses. y

' It is an object 'of the inventionto provide an eiiicient and comparatively .inexpensive apparatus, for the purpose specified, that will be convenient to use and easy to control.

21o. Other objects of the invention and thefeatures` of novelty willbe apparent fromuthe following. description ytaken in connection with the accompanying drawing, of whic'hfm t Fig. 1 is a side elevation of an apparatus 715 embodying my invention with certain parts A shown in section and other parts broken away; Y

The extension 17 has :735 an offset .18 on which a tubular. handle 19. is threaded, as indicated at 20. .fAn'air supply pipe 21 is secured to the offset 18,'and wit in thehandle 19, as indicated at 22, any7 suitable form of coupling. There is a passage 23 T through the extension 17 and a passage 24 in. the oiset 18, these two passages merging into,

an enlarged chamber 25. Alsleeve 26 is secured to the' oiset 18 by the threads V27 and carries av valve 28 which cooperates with a '245 Yseat at the inner end of the sleeve.` Leakage of air around the sleeve is prevented by the gasket 26.A The valve 28 has a stem 29, on the outer end of which is a button 30 that is adapted to b e actuated by the thumbof the` ".50 operator when his handL gripsthe handle19.

It will'be v understood, of course,that the cap13v can be Y'rotated only' when the nut 51'is loosened but `when the desired position of the caphasbeen 'determined,fit'may be secured in this position "byti'ghtening the nut 51'.. Y f Y l A plug 58 is screwedinto the threadedre- 'cess v56 and has at its' innertend a seat for the v ball check valve 59 which is y,adapted toclose the ort 60 inthe plug58. There is a port 61,1;lirough the end wall of the cap 13,'which establishes communication between the inrecess 53. When the apparatus isused yfor spraying,air is drawn into the container 10, thr'gugh the ports 57 60 and 61,'L to relieve the vacuum that 'would otherwise be created in thelcontainer and the valve 59 prevents j whenever the apparatus isV turned upon its side;l Y j v The bodymember 16has a'chamberv 62 that Y the tubes 42'and 43 and portsj63jare provided on opposite sides lofy the space 44 for establisho ing communication.betweenthe chambers y50 f and 62. rIhe nut 51 has aseatfor the'ball checkvalve 64and carries a tube 65 which M45extends' to apoint adjacentthe bottom ofvv Nthe lcontainer 10y so that 'the liquidwill be l drawn through this tubev into the nozzle member and thus practically all ofthe liquid in the container maybe utilized. iIn vthe 'operation of the apparatus, the tip 47 is directed towardthe object to be sprayed and the operator depresses'the button to openV j the valve28'. yThis admits airY to the nozzlel member andthe suction created by the stream ,t
